WATE R- ELEVATOR.

SPECIFICATION forming To tizi whom t may concern:

Be it known that I, ANDREW J. ENGLISH, a citizen of the United States,and a resident of Cincinnati, in the county of Hamilton and State ofOhio, have invented certain new and useful Improvements inVVater-Elevators, of which the following is a specification.

My invention relates to an improvement in water-elevators adapted toraise water and force. it through a system of pipes by gravity acting ona descending'v piston the cylinder of which is the reservoir, and isfilled by raisingv the weighted piston, which acts as a valve to fillthe cylinder.

In water-elevators hitherto employed, when the piston is wound up, anindependent wastepipe, to allow the waste above the lower packing andaround the piston to run back, is employed. My improvement works awastevalve in the service-pipe automatically by the movement of theclutch-arm throwing the winding mechanism into and out of gear. Anotherimprovement consists in utilizing the waste-pipe employed as such inwinding for the supply-pipe in forcing water, thereby taking water fromnear the top of the cylindercliamber, instead of at the bottom by anindependent pipe, as hitherto used.

Another feature of my improvement conssts in an automatic stop attachedto the winding mechanism. A Y

Another feature of my improvement relates to an adjustable top packing,which insures a perfect water-tight upper joint, which is anindispensable requisite in a water-elevator.

' Figure 1 is a central vertical section of my improvement. Fig. 2 is abroken cross-sec tion of myimproved packing. Fig. 8 is a side elevationof my automatic winding stop. Fig. 4o

4 is a detail of the split packing-ring.

A represents a cistern vor well, in which my elevator is suspended. Itmay be set at any distance above the water, not exceeding twenty-sevenfeet.

B represents a curb or platform covering the well, to which my elevatoris preferably attached by means of boltrods c, secured to crosshead t,which is secured by bolt-rods b b to rods c c, supporting cylinder C.This cylinder may be made of wood or of metal, and suspended in anywell-kn own manner.

resents apiston, which is provided with two cup leather packings, el d.

Fig. l shows the ordinary cup-packing secured to the cylinder andpiston, and Fig. 2 shows my improved form of packing, which will behereinafter described. Y

e represents an annular space around piston D, between the cup-valves dd.

E E represent weights, preferably connected by a cross-head, Ff', andattached to piston D.

F represents a rope, one end of which is connected to cross-head b,passing over pulley f on the cross-head E, and around windlass G, forelevating piston D.

g represents a shaft journaled to curb H.

I represents a gear-wheel loosely journaled on shaft g.

J represents a pinion keyed upon crank= shaft K.

L represents a clutch formed on the sleeves` of windlass G and gearsI.

M represents a bell-crank lever pivoted to the curb H, and provided withan arm, m, for sliding gear I in and partly out of meshwith gear J. Thearm h of lever M is attached to a cord, '1), which passes around afriction-roller, Z, and is attached to the arm of aweighted lever whichis used to open or close the waste cock or valve p, which is attached towastepipe N, which connects with service-pipes l? and P. Theservice-pipe P, for conducting the water-supply, enters theupper-portion of the cylinder C, so as to communicate with the annularspace c between the cylinder and the piston, and at the upper end of theservicepipe P is a branch pipe, P, for connecting with the system ofpipes through which the water is conveyed to the points desired. Acheck-valve, Q, is arranged in the service-pipe P', and opens upwardunderl the pressure of the water derived vfrom the weighted piston, saidvalve closing under the pressure of the water standing in the pipe Pwhen the pis ton descends in the cylinder.

R represents a waste branch val-ve or cock for emptying theservice-pipes, to prevent freezing, or for any other cause.

q represents a rod suspended inguide-ears n, attached to curb H. Vhenthe weights E and cross-head E are raised to the highest point,cross-head E strikes the lower end c IOO ' bent bell-crank lever n andforces a catch on arm a into the teeth of gears J and I, and arrests thefurther winding.

My improved upper packing is illustrated in Fig. 2, which is enlarged toshow more fully the construction.

o" represents a cap screwed to the cylinder C, which covers theadjusting packing-screws and holds cup-ring d in position.

'U represents a packing-ring suspended on screws s, which tap the same.

t represents holes bored in an annular ilange, a, to admit water intothe space to hold the leather d against piston D.

W represents a packing-ring made of suitable material, which acts as abearing-surface ,for the piston D. Said packing-ring XV is 2o is drawnup against flange u, contracting ring WV around piston D. This form ofconstructing the packing secures a tight joint and prevents thepacking-leather d from dropping away from-the piston, or the water fromentering between the packing d and piston D. rlhe annular projectingedge of the cup-packing d', at the lower end of the piston, on itsdescending movement, does not tightly iit the interior of the cylinder,but provides a space between the edge of the packing and the cylinder,so that the water rises upward through the said space to iill theannular space c, and thence through the service-pipesP P. Vhen thepiston is raised against the pressure of the water above the packing d',the edge of the latter is forced outward to bear closely against theinterior of the cylinder, whereby a vacuum is created under the piston,the

- lower valve is opened, and the cylinder is filled below the piston.

My device is operated as follows: Fig. l represents gear I in mesh withgear J, for win ding up the weights E and piston D. Valve p is opened,theweight O being raised, so that as. pistonD is elevated the water inspace c passes out through pipes P N and drops into the well A. As soonas weights E and crossure is relieved from the check-valve Q by openinga cock in the service-pipe P, allowing the weighted piston D to descend,which will force water upward around the lower cup-ring, d, into spacec, from thence through pipe P P into service-pipe P. The closingv of theservice-pipe arrests the descent of the weighted piston, and check-valveQ closes, preventing the waste of water from the servicepipe when valveor cock is opened for winding at the piston D."

I claimp l. The combination, in a water-elevator, of the cylinder C,having the packing d at its upper portion, the weighted piston D, havingat its lower end a packing, d', the edge-of which projects and isflexible, said cylinder and piston being arranged so as to provide theintervening space, e, and the service-pipe P, leading directly from theupper portion of the intervening space to the system of waterservicepipes, said packing d" on its descent admitting the full water-supplybetweeny it and the cylinder into the intervening space and to theservice-pipe connected therewith, and on its descent being forced out bythe water-pressure above it to closely lit the cylin- 1 der,substantially as described.

2. The combination ofthe piston D and cylinder G, arranged so as toprovide the intervening space, e, the water-supply pipe P, connectingwith the said-space, the branch pipes P P, and the waste-pipe N, havingthe weighted Valve p, with means for closing the valve p against theaction of its weight, substantially as described.

. 3. The combination of the cylinder C, weighted piston D, a drum, G,and rope for raising the piston, a clutch, L, means for operating theclutch, a service-pipe, P, a valve, p, in the waste-pipe, and means forclosing the said valve by the disengagement of the clutch from thewinding-drum to permit the weighted piston to descend, substantially asdescribed.

i 4. The combination of a cylinder, C, va piston, D, therein, a weightedcross-head, E', winding-drum G, winding-gears I J, pivoted armn, havinga catch to engage the gears, and slide-rod q, substantially asdescribed.

5. In combination with the cylinder and piston D, the adjustablepacking-ring fu, split ring NV, and the cup-packing d, substantially asherein set forth.

6. The combination, with the cylinder vC and piston D, of a cup-packing,d, the annu- IOO IIO

lariiange a', having the orifice t, and the adjustf able packing-rings oWV, said orifices serving to admit water over the ring W to press thecup-packing d against the piston, substantially as described.

In testimony whereof I have hereunto set my hand.
